Proper hand signals, a positive and alert attitude, and a "good eye" for procedures can lessen the risk of accidents or injuries to co-workers. Daily Safety The designated signal person must be competent and know "all the right moves". As well, the signal person must wear a high visibility vest. armlet, or other clothing that clearly identifies them,. A hand signal chart should be mounted on the crane unit so everyone knows the system. Crane, derrick, and hoisting equipment must be inspected daily. Be on the lookout for faulty equipment such as cracked windshields or a leaking hydraulic line. Good housekeeping on and near the crane area is essential for safety.

More than one will confuse the operator. Also:

Every worker should know crane hand signals. Knowing the signals may allow you to help out when needed If you are asked to be a signal person, make sure you are using the same signals as other workers and operators on the project With tower cranes or situations where hand signals are not safe enough, ensure that a twoway radio is used for voice communication. This will give you direct contact with the operator. Whatever system you use - hands or radio - make sure the equipment and workers are able to do the job right.
